Kia Sportage knocking problems

Filed Nov 3, 2026 · Engine · KS

My vehicle experienced a catastrophic engine failure, losing power on the roadway. The vehicle is currently located at the Kia dealership, and I have been provided a formal Repair Order showing an active Diagnostic Trouble Code (DTC) P1326. Kia Corporate and the dealership are currently denying coverage under the In re: Hyundai and Kia Engine Litigation Class Action Settlement, claiming that the "VIN shows clean with no open issues." This is a fundamental misinterpretation of Kia's internal database. The VIN shows "clean" because the mandatory Product Improvement Campaign PI1806 (Knock Sensor Detection System / KSDS) was successfully completed on my vehicle on November 13, 2019. I hold physical, printed proof of this completed campaign from a certified Kia dealership. Under the terms of the court-approved settlement and Kia's own Technical Service Bulletins (TSBs): 1. Completion of the KSDS update (PI1806) qualifies the vehicle for a Lifetime Short-Block Warranty Extension against connecting rod bearing failure. 2. An active or history P1326 fault code mandates that the dealership perform a digital Bearing Clearance Test (BCT) and submit a Prior Authorization (PA) package to corporate for an engine replacement. By refusing to look at the historical campaign completion data and denying my claim based on a "closed/clean" status, Kia is actively violating the court-mandated terms of the settlement.

My 2016 Kia Sportage LX experienced a catastrophic engine seizure on September 9, 2026, at 91,249 miles. My son was returning home on I-95 South in Florida. After exiting at Sample Road and traveling west near Seabra Foods at approximately 40 mph, he first noticed unusual engine noises at an estimated 91,245 miles. He pulled over, immediately called me, and sent a video recording of the noise. I advised him to proceed to Bisbee Auto & Tires, an independent repair facility. The engine completely seized directly in front of its service entrance at 91,249 miles. Most concerning, my son reported NO dashboard warning lights, including the check engine light, before the engine seized, despite Kia's service records confirming that the Knock Sensor Detection System (KSDS) update had been completed before the failure. KSDS is intended to detect certain vibrations associated with connecting rod bearing damage. I request investigation into why no warning appeared, whether KSDS operated correctly, whether diagnostic code P1326 was recorded, and the actual engine failure mechanism. My son regularly drives on I-95 at 65 mph. Had the engine seized in highway traffic, sudden loss of propulsion could have caused a serious collision, injuries, or death. Bisbee Auto & Tires informed us about potential lifetime engine warranty coverage and directed us to Kia rather than charging approximately $6,000 for an engine replacement. Kia replaced the engine under warranty in September 2026. On October 13, 2026, Kia Corporate confirmed that the replacement was the same engine type but could not identify engineering improvements, revised bearings, or whether it was new or remanufactured. I request the federal safety agency investigate this engine seizure, the absence of KSDS warnings despite the completed update, similar incidents, and whether additional safety measures are warranted. Service records and video evidence are available upon request.

The vehicle suffered a primary connecting rod bearing failure covered under the Theta II class action warranty campaign. A brand-new warranty engine long-block was installed by an authorized dealership. Immediately upon vehicle pickup, the brand-new engine began exhibiting an un-metered acceleration defect. While stationary and idling in Park (P), the engine aggressively revs on its own without any operator input on the gas pedal. This malfunction caused the vehicle to violently surge and physically lurch forward several inches while in Park. This un-metered acceleration is an active, unpredictable driving hazard both in parking environments and in traffic, posing an immediate risk of a collision or pedestrian injury. The manufacturer has been notified but has failed to transmit a diagnostic pre-authorization to an alternative service center to safely inspect this powertrain hazard.

The vehicle suffered a sudden, catastrophic mechanical engine failure while driving. The vehicle completely lost acceleration, entered a low-pitched humming 'limp-home mode,' and the dashboard red oil pressure warning light illuminated solidly.The vehicle had previously received the mandatory corporate KSDS software update. A diagnostic check by an authorized Kia dealership officially documented the physical evidence of 'metal debris in the engine oil,' which is the unarguable signature of the defect described in the federal safety agency Recall campaigns for the Theta II engine block.Despite the physical evidence of connecting rod bearing failure and the active KSDS update, Kia Corporate and the local dealership have issued a flat denial of the Lifetime Warranty engine replacement mandate. This constitutes a direct violation of the safety recall settlement framework."
